    I am using Lumia-920 and I have problem synching the account now.
    Suddenly it stopped syncing my Microsoft Account and keeps giving me error 850100D.

    I tried restarting.
    Changing the mail server from original to 100 other and came back to the one I was using.
    (I am using mail server showing in hotmail's address bar...Hope I am correct)

    What else I can try...there is no website where this topic is listed with proper solution....

    Help!!!!!!!!

    Is this after resetting your phone and restoring settings? If it is then delete the account from 'email & accounts' and then add it again from fresh

    No I did not change the password nither I restored the settings.

    And this is my primary account there is no separate Hotmail account as I see here.

    And I am worried if I delete the primary account will it affect my apps and other part of eco systems like skydrive and all?

    I am able to login through web interface. Just sync on phone is not working

    And now it is showing error "85002004".
    This is kind of odd behaviour.

    Question: How do I remove primary windows phone account? It is not giving me any option to do that!!

    Is it a hotmail id? And primary accounts cannot be removed until you do a hard reset.

    Make sure you have your date and time settings correct.
    Make sure you have the correct password and email username.
